A new website from Inkifi has created a tool that can calculate how much your Instagram posts are worth based on your number of followers.Business Insider’s lifestyle reporter tested it – and her posts turned out to be worth very little.Micro-influencers with as few as 3,000 followers, though, are charging brands as much as £100 ($130) a post.

It can feel unfair heading to a 9-to-5 job each day when some people are there travelling the world for free, getting paid large sums to take photos of themselves in incredible destinations.

But if you’ve always aspired to live the influencer lifestyle, there’s a simple way to find out whether your profile would make the cut.

A new website from Inkifi has created a tool that can calculate how much your Instagram posts could be worth based on your number of followers – you just type in your Instagram handle.

And don’t be fooled into thinking you need hundreds of thousands of followers to have a chance of earning any cash.

“Micro-influencers,” people who have as few as 3,000 followers on the photo-sharing app, are charging some brands to feature their products in Instagram posts. The influencer marketplace Tribe told Business Insider that micro-influencers with 3,000 to 10,000 followers could charge brands £50 to £100 ($65 to $130) for a post, while people with over 100,000 followers could demand more than £350 per photo.

I do not fall into that category, sadly, and have a modest following of just over 400.

Inkifi used data from “The State of Influencer Marketing 2017” report and calculated that, on average, each Instagram follower was worth £0.0043 – though it noted that deals between influencers and brands differ.

So to find out my worth to brands, I entered my Instagram username on the Inkifi site.

But it’s still something to work from. Elma Beganovich, a 31-year-old “superstar influencer” who has over 735,000 followers on Instagram, told Business Insider that things could ramp up pretty quickly once you’ve applied yourself.

Beganovich and her sister quit their corporate jobs in 2013 to become social-media personalities – something that barely existed at the time.

Beganovich told Business Insider that over two years, she and her sister went from charging brands £75 for a single sponsored post to an enormous £15,000.

Below is an example of a collaboration Beganovich recently did with The Pierre, the five-star hotel that’s the iconic US flagship of Taj Hotels on New York’s Fifth Avenue.

According to Inkifi, based on her follower count, Kim Kardashian could make £448,100 from just one Instagram post, while the supermodel Gigi Hadid could earn £156,100. However, their names alone are likely to come with a bigger price tag for brands.

It’s also worth noting that those in the know in the influencer-marketing world say your worth to brands is based on more than just your follower count.

“Now the metric brands should be looking at is the cost per engagement – the cost of the post divided by the number of comments, likes, and shares – because these days anyone can buy reach,” Lisa Targett, the UK general manager of Tribe, told Business Insider.
